【Abstract】 The question of eliminating distorted current from power networks with activepower filters is investigated. The effects of output current follow up errors on compensation perfor-mances are analyzed,and approximate calculation formulas for the parameters are deduced. A newcontol method for solving the time delay problem of the compensating current is also presented, Thefilter’s validty has bean verified through an labaratory experiment.更多还原
